## Description

- description: 'We reassess the structure of the effective action and quantum critical
    singularities of two-dimensional Fermi systems characterized by the ordering wavevector
    Q= 0. By employing  infrared cutoffs on all the massless degrees of freedom, we
    derive a generalized form of the Hertz action, which does not suffer from problems
    of singular effective interactions. We demonstrate that the  Wilsonian momentum-shell  renormalization
    group (RG) theory capturing the infrared scaling should be formulated keeping
    Q as a flowing, scale-dependent quantity. At the quantum critical point, scaling
    controlled by the dynamical exponent z=3 is overshadowed by a broad scaling regime
    characterized by a lower value of z approx 2. This in particular offers an explanation
    of the results of quantum Monte Carlo simulations pertinent to the electronic
    nematic quantum critical point.  '
